Project Labor Agreements. Building and construction trades workers are one of the hardest hit groups in the nationâs job crisis. Yet state lawmakers, backed by construction industry CEOs, want to cut the wages of those workers by eliminating prevailing wage laws and project labor agreements (PLAs) on public construction projects.
There are many algorithms to solve scrambled Rubik's Cubes. The maximum number of face turns needed to solve any instance of the Rubik's Cube is 20, and the maximum number of quarter turns is 26. These numbers are also the diameters of the corresponding Cayley graphs of the Rubik's Cube group. An algorithm that solves a cube in the minimum number of moves is known as God's algorithm. There are two common ways to measure the length of a solution. The first is to count the number of quarter turns. The second is to count the number of face turns.
ErnÅ Rubik (Hungarian: [Ërubik ËÉrnÃ¸Ë]; born 13 July 1944) is a Hungarian inventor, architect and professor of architecture. He is best known for the invention of mechanical puzzles including Rubik's Cube (1974), Rubik's Magic, Rubik's Magic: Master Edition, and Rubik's Snake. While Rubik became famous for inventing the Rubik's Cube and his other puzzles, much of his recent work involves the promotion of science in education.
